Mach → TAS (actual)
TAS from cruise Mach and the probe's total air temperature; static OAT is backed out of the ram rise.
Reading the screen: cyan is a value you entered, green is a computed result, amber means a field still needs input or the entry needs a CHECK. SOLVED lights when every result is computed; STO keeps a value to reuse in another function; the line-select keys beside the screen pick the field the keypad edits.
Labeled assumption — Assumes full temperature-probe recovery (K = 1.0), matching the CX-3's Actual modes. Real probes recover less than 100% of ram rise, so derived OAT and TAS shift slightly with the installation.
TAS from cruise Mach and the probe's total air temperature; static OAT is backed out of the ram rise. Reproduces the ASA CX-3 manual's Actual Mach example (M 0.82, −20 °C TAT → 477.3 kt, −58 °F OAT) with the K = 1.0 recovery the CX-3 implies.
